**Circuit Description and Analysis**

**Voltage Source:**
\[ v(t) = 4 \cos(10^4 t + 30^\circ) \, \text{V} \]

**Circuit Components:**
- A 60 kΩ resistor is connected in series with the voltage source \( v(t) \).
- A 2 nF capacitor is connected in parallel with the series combination of the resistor and the input to an operational amplifier (op-amp).
- The op-amp is arranged in a feedback configuration.
- The output of the op-amp is connected to a 110 kΩ resistor.

**Current Notation:**
- The current through the 110 kΩ resistor is denoted as \( i_o(t) \).

**Operation:**
The circuit demonstrates a complex AC signal being processed through a combination of resistive, capacitive, and operational amplifier components. The op-amp likely functions in a filtering or amplification role, influenced by the chosen resistor and capacitor values.

**Note for Students:**
Understanding the role of each component will help you analyze the frequency response and potential practical applications of this circuit.
